Elisha Wiesel, chief information officer at Goldman Sachs, said one or two employees have approached him so far about what President Trump’s immigration order might mean for them.

Wiesel, the 44-year-old son of Holocaust survivor Elie Wiesel, understands their concern. He spoke in an interview Sunday at the Museum of Jewish Heritage, where he was attending a reading of “Night,” his father’s account of his experiences in Nazi concentration camps. Across the street in Battery Park, thousands of people had gathered to protest Trump’s order.

“What all the marchers are doing — that’s just as much a part of his legacy as ‘Night,’” Wiesel said of his father, who died in July at 87.
